Knowledge that Transforms

ABSTRACT This paper decomposes daily close to close returns into trading day and non‐trading day returns. We discover that all of the average negative returns from Friday close to Monday close documented in the literature for stock market indexes occurs during the non‐trading period from Friday close to Monday open. In addition, average trading day returns (open to close) are identical for all days of the week. January/firm size/turn‐of‐the‐year anomalies are shown to be interrelated with day‐of‐the‐week returns.

ABSTRACT Levy and Markowitz showed, for various utility functions and empirical returns distributions, that the expected utility maximizer could typically do very well if he acted knowing only the mean and variance of each distribution. Levy and Markowitz considered only situations in which the expected utility maximizer chose among a finite number of alternate probability distributions. The present paper examines the same questions for a case with an infinite number of alternate distributions, namely those available from the standard portfolio constraint set.

ABSTRACT In this paper a discrete mixture of normal distributions is proposed to explain the observed significant kurtosis (fat tails) and significant positive skewness in the distribution of daily rates of returns for a sample of common stocks and indexes. Stationarity tests on the parameter estimates of this discrete mixture of normal distributions model revealed significant differences in the mean estimates that can explain the observed skewness and significant differences in the variance estimates that can explain the observed kurtosis. An alternative explanation for the observed fat tails is the symmetric student model. The result of a comparison between the models is that the discrete mixture of normal distributions model has substantially more descriptive validity than the student model.

ABSTRACT This study of financing decisions by U.S. corporations examines the issuance of long term debt, issuance of short term debt, maintenance of corporate liquidity, issuance of new equity, and payment of dividends. Given costs and imperfections inherent in markets, a firm's financial behavior is characterized as partial adjustment to long run financial targets. Individual firm data are used so that speeds of adjustment are allowed to vary by company and over time. The results suggest that financial decisions are interdependent and that firm size, interest rate conditions, and stock price levels affect speeds of adjustment.

ABSTRACT An analytic solution to the American put problem is derived herein. The hedge ratio and other derivatives of the solution are presented. The formula derived implies an exact duplicating portfolio for the American put consisting of discount bonds and stock sold short. The formula is extended to consider put options on stocks paying cash dividends. A polynomial expression is developed for evaluating these formulae. Values and hedge ratios for puts on both dividend and nondividend paying stocks are calculated, tabulated, and compared with values derived by numerical integration and binomial approximation. As with European options, evaluating an analytic formula is more efficient than approximating the stock price process or the partial differential equation by binomial or finite difference methods. Finally, applications of this American put solution are discussed.

ABSTRACT This paper examines the relation between the interest rate sensitivity of common stock returns and the maturity composition of the firm's nominal contracts. Using a sample of actively traded commerical banks and stock savings and loan associations, common stock returns are found to be correlated with interest rate changes. The co‐movement of stock returns and interest rate changes is positively related to the size of the maturity difference between the firm's nominal assets and liabilities.

ABSTRACT This study uses a longer time period and additional stocks to further investigate the weekend effect. We find consistently negative Monday returns (1) for the S & P Composite as early as 1928, (2) for Exchange‐traded stocks of firms of all sizes, and (3) for actively traded over‐the‐counter (OTC) stocks. The OTC results are based on bid prices and therefore appear to reject specialist‐related explanations. For the 30 individual stocks of the Dow Jones Industrial Index, the average correlation between Friday and Monday returns is positive and the highest of all pairs of successive days. The latter finding is inconsistent with fairly general measurement‐error explanations.

ABSTRACT In this paper, empirical evidence with respect to both the direct and indirect costs of bankruptcy is assessed. This should be of interest for three related reasons. First, there is a need to provide further evidence as to the size of bankruptcy costs. Second, for the first time a proxy methodology for measuring indirect costs of bankruptcy is presented and actually measured. Third, a simple format for measuring the present value of expected bankruptcy costs is compared with the present value of expected tax benefits from interest payments on leverage. This comparison has important implications for the continuing debate as to whether or not an optimum capital structure exists for corporations.
